Premium design. Constructed from high-quality aluminum, these roller rocker arms are not just an upgrade but a performance revolution.

Easy installation. Installation is a breeze with the 3/8" stud, ensuring a secure fit that withstands the demands of high-performance driving. With the 1.6 ratio, these rocker arms deliver precise valve lift, optimizing airflow for improved combustion efficiency.
